Salmon passage has been in the media quite a bit lately. Although efforts to replace culverts that block salmon passage have been ongoing for years, a March 2013 ruling by a federal judge is likely to step up this effort in Washington State.
One of the programs that already exists to address this problem is the Washington State Family Forest Fish Passage Program (FFFPP) is a cost-share program that helps small forest landowners correct fish passage barriers on their forest lands. The program provides 75-100% of the cost of correcting a barrier; it also provides technical assistance. The program is implemented by three state agencies; DNR, WDFW, and the Interagency Committee for Outdoor Recreation/Salmon Recovery Funding Board (IAC).
